SafetyQuestion 671 of 700
An electrician will work near energized conductors up to 20 kV. Which class of hard hat is designed to protect against that level of electrical contact?
a.Class G (General)
b.Class E (Electrical)
c.Class C (Conductive)
d.Class C with a metal shell for durability
Explanation
Correct: Class E (Electrical) hard hats are tested to withstand roughly 20,000 volts and are intended for electrical work. Class G (General) is tested only to about 2,200 volts, so it is inadequate near 20 kV. Class C (Conductive) offers no electrical protection at all and may contain conductive material. A metal-shell hat would increase the shock hazard, not reduce it.
